00 00 11111D
The display data appears when D is 1 and disappears when D is 0.
Though the data is not on the screen with D=0, it remains in the display data RAM.
Therefore, you can make it appear by changing D=0 into D=1.
5.2 Set Address (Y Address)
RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0
0 0 0 1 AC5 AC4 AC3 AC2 AC1 AC0
Y address (AC0~AC5) of the display data RAM is set in the Y address counter.
An address is set by instruction and increased by 1 automatically by read or write
operations of display data.
